Go 如何将条带指向条带模拟本地服务器？

我正在使用执行条带操作，例如创建新客户、添加信用卡、创建订阅等。我想进行端到端测试。有一个模拟HTTP服务器，它的响应类似于真正的条带API。我在终端本地运行。我如何指向我在go应用程序中使用的stripe go来调用这个模拟HTTP服务器，而不是真正的stripe API

在stripe go文档中有以下内容

// Setup
stripe.Key = "sk_key"

stripe.SetBackend("api", backend) // optional, useful for mocking

我是否应该传递一些特殊的东西作为

后端

，以便stripe go知道然后调用哪个是stripe mock的地址

这是条带。收进

// SetBackend sets the backend used in the binding.
func SetBackend(backend SupportedBackend, b Backend) {
    switch backend {
    case APIBackend:
        backends.API = b
    case UploadsBackend:
        backends.Uploads = b
    }
}

// Backend is an interface for making calls against a Stripe service.
// This interface exists to enable mocking for during testing if needed.
type Backend interface {
    Call(method, path, key string, body *RequestValues, params *Params, v interface{}) error
    CallMultipart(method, path, key, boundary string, body io.Reader, params *Params, v interface{}) error
}

这是

后端

// SetBackend sets the backend used in the binding.
func SetBackend(backend SupportedBackend, b Backend) {
    switch backend {
    case APIBackend:
        backends.API = b
    case UploadsBackend:
        backends.Uploads = b
    }
}

// Backend is an interface for making calls against a Stripe service.
// This interface exists to enable mocking for during testing if needed.
type Backend interface {
    Call(method, path, key string, body *RequestValues, params *Params, v interface{}) error
    CallMultipart(method, path, key, boundary string, body io.Reader, params *Params, v interface{}) error
}

从内部看，公开的

后端配置

结构实现了

后端

接口。因此，以下措施应该有效：

httpClient := &http.Client{Timeout: defaultHTTPTimeout}

mockBackend := &stripe.BackendConfiguration{
      "api", 
      "http://localhost:12111", 
      httpClient,
}

stripe.SetBackend("api", mockBackend)
